(Actually we never paid that much attention to greeting card holidays. So if they dont call, it's my fault in raising them to be all around skeptics.)
I'm glad you brought up your grandfathers. Both of mine led very difficult lives and made great sacrifices so that their children and grandchildren could have a better chance than they did. Whenever I have doubts about my project (which isn't often), I remind myself that they came here so that I could do this. Kinda puts things in perspective.
I'm with you on the grandfathers too... It makes me proud to think of all the ancestry behind me - behind everyone really. All the people who have worked so hard to get us and the rest of humanity to this magical time.
Sometimes when I'm feeling down, I watch this little clip on youtube - I don't have an ounce of Viking ancestry, but I like the message:

Lo, there do I see my father.
Lo, there do I see my mother.
And my sister and my brother
Lo, there do I see the line of my people
Back to the beginning.
Lo, they do call to me.
They bid me take my place among them
In the halls of Valhalla
Where the brave may live forever.
So it is with life. Perhaps in the long run we'll all be dead and the universe will cave in, but in the meantime the things we do and say matter, and there is beauty in the world to appreciate. So I went to the boardwalk with my father and brother and we all had a terrific time, and having a good time was reason in itself to do it.
Once you give up the religious/gamers' view that everything you do has a score, you can appreciate things for what they are rather than for any ultimate result.
It's a convenience. ;)
Play with your kids, if you have them.
Hug your father, while you have him.
Bottom line, I'm kidding around. You can give me the benefit of the doubt of making a little joke with no ill-intent... or you can call me an asshole. I'll leave it up to you to decide which is worse.
